The present invention relates'to acable reel for miningmachines and has for its object to provide astructure for winding and unwindingelectric conduits-used, in conn'ec-Q 8 tion with electricallyoperatingfniining ma-g chinery remote from the car. f V r 7 Another important obj ect of the invention resides in the provision ofra reel of this; nature which is simple in its Construction,

inexpensiveto manufacture, strong and durable, thoroughly efficient and'reliable in use and operation, and .otherwis'e well adapted to the" purpose for whichit is designed.

Withthe above andn'umerous other, ob-

, 1 jects in View as will appear as the descrip-' 7 tion proceeds, the invention' 'resides" in certain novel features ofconstructiomiand in the combinationfand arrangement of arts as will be hereinafter more fully described and 9 claimed. r

Figure 5 is a sectional'view taken substan-- tially on the line 55 of Figure 3.

Referring .to the drawings in detailit will be seen that from one end of the car or mining machine 5 there eXtendshorizonta-llya U-shaped frame 6, on the sides of which are 7 from the frame as at 9 and; electricallyconnected with the source of electrical nergyby means of a lead-10. r i A Numeral 11 denotes a core of'insul'ating material having bores 12"extending inwardly from the ends thereof'a'nd terminatingyequidistant from the 7 center thereof: Disks v 14 are mountedfon reduced end portions of the i core 11 and have cylindrical hubs-15 directed inwardly therefrom and anchored v in place ;by means of screws;v or other fastening ele-; ments 16. Trunnions and 21 are formedon shanks 1 22 and 23irespectively which are formedwith' chinery'. I

- tionthereof. i g I I i The'present embodiment of the invention has been disclosed in considerable detail merebearings 7 and 8, the latter being insulated ducting material and having reducedend por i shanks extending into bores and formed 1930. Serial 110,434,324, w v longitudinally extending ribs 24 to be received injlongitudinally extending grooves formed inthe' bores 12. The inner ends of the shanks are provided with openings for receiving bolts 25 to which the cables 26 are a engaged. g I a i v I A On thetrunnions 21 there is keyed a pulley i 1 27' operatively connected withv anelec'tric motor'2 8 in. the machine or-car 5 by means of a pulley29'and belt 30. The cable 26-to the left of 'Figuresl and 2, is grounded through 7 the shank 24, the'fraln'e 6, etc, and-maybe I used asa ground wire for the electric machiny W i e the'other wire 26 'to theright of eads thecurrent to the ma- V 4 these figures 'It isthought that'the construction, operation, utility and advantages of this invention, 'f;'

will now be quite apparent to those skilled,

this art without a more detailed descriply for the purposes of exemplification since in actual'practiceit attains the features of advantage enumerated" as desirable in th g I tatement of the invention and the above d 'scription; t i v g i It will be-apparentthat changes in the details of construction, and in thejcombination and arrangement of parts may be resorted to without departingfrom' the spirit orscope of the inventionashereinafter claimedor sacrificing any of 'itsadvantages. j

Having thus described my invention, whatii Iclaimas'newis: p g a I i. In a reel structure of the class described for electric cables, a core formed of non-contions, apair of end disks having inwardly directed oylindrical collars at theircentersfit (I ting on the reduced portions, means for de:

tachably connecting. the Zc ')llarsf" to the rej duced portions, said corefbeing provided'with a pair ofinwardly 'directedibores from the ends thereof terminating equidistant from; i, the'center th'ereof,-.thegwalls of theboresjbei V ing provided 'rwith'aplurality: of-longitudi f nally extendin g ooves; trunnions'ha vfing Y with longitudinally extending ribs to be received in the grooves, and bolts extending transversely partly through the core and the inner ends of the shanks having openings therein to receive the inner ends of the bolts, the outer end of each bolt projecting from the core for forming a terminal for a conductor.

In testimony whereof I affix my signature. v
